| Abstract: | With consideration of the non-linearity,complexity,and uncertainty of the prediction problem in demand in world shipping,a new prediction model for demand in world shipping based on LS-SVM(least squares support vector machine) was put forward.A concrete prediction experiment for demand in world shipping was carried out.Compared with some other models,the model proposed proved to be higher in forecasting speed and accuracy,and easier to realize. |
